GRAIN-BINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 258,204, dated May 16,1882.

Application inea January 1r, issa (Modem I all whom it may concern:

Be it known that I, JosEPn R. Pnnsoo'r'r, of Beaver Dam, in the countyof Dodge and Sta-te of Wisconsin, have invented certain Improvements inGrain-Binding' Machines, of which the following is a specification.-

My invention relates to a grain-binding attachment lnore especiallyintended for use in connection with reaping-machines, but which may alsobe applied to harvesters.

The improvements consist in pivoted arms arranged to liedown close tothe grain-receiving table while* the grain is being received, and torise and to throw the grain forward when the gavel is lo be formed; in acord-carrying and gavelin g arm, provided with a cord-holder andarranged to fall and to remain normally beneath the grain-tab1e, but torise and advance with the grain delivered by the pivoted arlns as thebinding operation commences; in a cutting device and a former, bothoperated by the nose orforward end of the cord-carrying arm, and

adapted to cut from a continuons strip of sheet metal a piece sufficientfor a clip or fastener, andV to bend the same into shape to receive theends or strands ot' the applied band; in a hammer which rises and fallswith the cutter, assists in forming the clip, and afterward serves `toclose the same; in a cord-cutter arranged to sever the applied band fromthe main supply of band material; in a bundledropper, and in variousother features and details, hereinafter set forth and explained.

In the accom panyingdrawings, Figure 1 represents a perspective viewofthe binding mechanism or attachment; Fig. 2, a face elevation,partlyin section; Fig. 3, a plan view; Figs. 4, 5, and 6, enlargedviews, showing the mannerof forming and applying the clip orfasteningtof the applied band; and Fig. 7 an en'- larged view of theclip-band feeder.

The object of my invention is to produce a simple and cheap bindingattachment, adapted for use in connection with theordinaryreaping-machine, thus avoiding the expense and the excessive weight of aharvester; and with this object in View I construct my machine in themanner shown in the drawings, in which- A representsa strong framework,which may be attached and secured in any convenient manner to thereaper, and is furnished with a main drive-shaft, B, which in practiceis connected with and driven by the drivewheel of the reaper, and servesto give motion to the various parts of the binding mechanism, ashereinafter explained.

Within the frame A, I arrange a sliding grain-table, C, which is causedto move toward the shalt B at suitable intervals, either by an arm orlever, E, connected with the lower side of the table and operated byacam ,F, as shown in Fig. l, or by a chain, a, winding upon a drum, D,as in Fig. 2, a spring, G, or a cord and weight heilig provided toretract the table C at the proper time. f

H represents the cord-carrying arm, which, with a similar arm, lI, iscarried by a hori- 'zontal shaft, b, the ends of which slide in groovesbeneath the grain-table C, said arms being curved, slotted, and arrangedto pass upward through openings c in the grain-table, being raised andlowered, as thetable moves back and forth, by transverse pins or boltsd, extending through the slots c and made fast to the sliding table, asshown in Figs. 1 and 2.

I I represent two arms, which are pivoted to the sliding table C, andprovided each with a foot, f, which, coming in contact with the end ot atrack or rail, J, as the table starts forward, causes the arm to risefrom its normal position and to stand upright, as` in Fig. l, the feettraveling upon the tracks andpre'; venting the arms from fallingbackward or forward. The arms I I, as above stated, lie down upon thetable C when the latter is in position to receive grain from the rakingor delivering mechanism, and the grain therefore falls upon them, and isthrown forward by the arms as they rise to a point in advance ot tirearms H H', which then rise, as before mentioned, and gather the graininto a gavel, while at the same time the arm H carries the band aboutthe grain.

The binding material, which will be preferably twine, is carried byaspool, K, any conimon form ot tension device being applied, either tothe spool or to the band passing therefrom, to regulate the paying outof the same, and a yielding take-up arm, such as is corumonly used inmachines of this class, being Vron employed to take up any slack that isoccai mechanism.

sioned by the operation of the machine, it found necessary'.

Lrepresentsthebinding-tableproper,hinged at one side, as shown in Fig.2, and furnished with a counter-weight, g, a spring or equivalentdevice, which holds it normally in a horizontal position to sustain thebundle while .heilig bound, the grain being delivered thereto by thearms H H as they rise above the grain* table C and advance toward thebinding-table. The binding-platform is connected with the grain-table,as hereinafter explained, so that as the latter recedes to receive afresh supply of gra-in the binding-platform is tipped and caused to dropthc bundle previously bound.

reel or box containing a long strip or ribbon,

.-L, of sheet metal, a feeding device for ad vanc- 'scent ing the sameacross a pair of formers, N, pivoted to swing horizontally n pou theupper face of the standard, a gravitating arm, 0, carrying a blade orcutter, t', and a die, j, which serves rst to bend the strip cutoff bythe blade t' between theformers N into thcform of the letter U, andsubsequently to flatten down the upright sides of the clip or fastenerupon the strands of cord carried between them by the cord-carrying armH, which latter continues on with the ends, carrying them past acordoutter, P, which seversv the applied band from the stock from whichit is drawn. l

Referring now to Fig. l, the formers N will he seen to consist of twoarms, bowed out and pivoted about midway between their ends to the upperface of the standard or bracket M, their forward ends being slightlycutaway on thc under side, and their rear ends heilig provided withbeveled lugs n and held normally together by a spring, It, thusseparating their forward ends, as shown in Fig. 4, in which positionthey stand when the strip h is fed forward to permit the necessarymaterial for a clip lto be cut from it. The strip being fed forwardacross the top face of the formers, the arnij O descends, the blade orcutter i severing the clip Z therefrom andthe die j bendingit into theform shown in Fig. 5 at the same de- It will be seen that one oftheformers serves as an anvil to support the strip while being cut, andthat its outer edge and the falling blade act in the same manneressentially as the blades of a pair of shears. rlhe rise. and fall ofthe arm O are effected and'eontrolled by the cord-carrying arm H, aspresently described.

The operation of cutting off the clip and bending it into U form iseffected as the cordcarryingarm recedes from the clip-applying` Hence,when the cord-carrying arm comes forward, bringing the two'strands ofthe applied band with it, the open clip is in position between theformers N, and, being directly in thc path of said strands, the latterare laid directly across and into the clip. A beveledlug or projection,m, on, the cord-carrying arm H then enters between the beveled lugs orprojections a of the formers N, throwing their forward ends together andfolding downthenpright sides of the clip, as in Fig. 6, the projection mpassing from between the lugs 'a and permitting their forward ends toseparate, at which moment the die or hammerj again descends and flattensthe clip upon the strands. The movement of the cordcarrying armcontinuing, the strands are car ricd across thepath ot' reciprocatingblade or cutter P and severed, as above mentioned'.

By again referring to Figs. 1 and 2 the con struction ot' thecordtcarryingarm and the manner in which it controls the fasteningdevices will be explained, itl being first stated, however, that the armO is pivoted to lugs on the bracket-top and extends directly across thepath of the cord-carrying arm, which passes underitin advancing undreceding. As clearly shown Iin said iigures, the arm is formed with apointed end and furnished on its upper side with a vertical rib,0,curvedor inclined downward at both ends, said rib being slotted horizontallyto receive a rib or guide-pins of a ,Sliding plate or block, Q, whichstands bythe side of and rises slightly above the rib o, as shown. Thelowercdge or face of the plate or block rests and slides upon a lateraleXtension, p, ofthe cordcarrying arm, and its upper corners are slightlybeveled or rounded, as shown. The plate or block is free to slide backand forth within the limits of the slot q.

From the foregoing it will be seen that as .the cord-carrying armadvances, its pointed nose passingjust beneath the arm 0, the arm willberaised by the inclined face of the rib o, and, coming into contactwiththe plate Q,will move the latter to the limit allowed by the slot g, andthen, raised by the beveled corner of said plate, the arm O will permitthe latter to ride under it to its end, when the arm will suddenly falland atten the strip through which the strands have been previouslylaidand which has been folded, as above explained. The cord-carrying armcontinues its motion until, reaching its limit and having performed itsfunctions in that direction, it starts back. In thus moving back theinclined rib o again raises the arm O, the plate Q, being, as before,moved to the end of its slot, butin the reverse direction, and the armOy again falls, cutting off and bending the clip l, the strip h beingfed forward, as the arm is raised, by the receding cord-carrying arm.

rJhe feeding device by which the strip h is fed forward may be avibrating lever, R, slot-- ted at one` end andcarryin g a block, r,through which the strip passes, the block being caused IOO IOS

IIO

to turn or swingl about its connection with the lever It, and to crampor lock upon the band hin going forward, but to move freely back uponthe same when the motion of the lever is reversed. y

The lever It may be operated by a cam, s, on a rock-shaft, S, or in anyother convenient manner, as may also the cutter P.

The cord or band for each bundle is drawn from the reel by thecord-carrying arm H, which, for the purpose of holding the end of thenew band, is furnished with a cord-holder, T, consisting of aspring-)ressed pivoted jaw,

Y t, and astationaryja-w, t', the forward ends of both being beveled orrounded-to cause the cord to be readily caught by them.

In starting the machine the jaws t t are separatcd and the end of thecord is placed between them. The cord-carrying arm, receding, draws oi`the required amount for the band, and after the grain has been deliveredin advance ot' said arm and across the band the arm, rising andadvancing, carries the band over the top of the grain, and, stilladvancing, comes in contact with the other strand or end of the appliedband coming from the reel, earrying said latter end before it across theU- shaped clip, laying both strands across and into the clip, whereuponthe arm O descends, and the fasten-ing of the vclip is completed, asbefore explained. Atthis moment the outwardly-projecting rear end of thepivoted jaw t,oon1ing in contact with a fixed arm, u, is pressed inward,causing the jaws to open and permitting the strand from the reel toenter, the advance of the arm causing said strand or end to be forced orwedged between the jaws sufficiently to insure its retention while `thepivoted jaw rides off the stationary arm u, the fact that the cord hangsfrom a point in rear of the cord-holder tending also to insure suchretention. Just after the second strand is thus seized the knife P isoperated and the applied band severed below the cord-holder, thusleaving the portion passing from the reel to the cord-holder intact andthe new endin the cordholder. The bundle is thus completely bound andits band severed from the stock on the reel. As the grain-table andcordcarrying arm recede, the latter being thrown down beneath the table,as explained, the binding-platform L is tipped or thrown down by meansof a chain or band, e, connected at one end to a crank, w, on therock-shaft S, and at the other end toan arm, w', depending from theunder side of said platform, the tipping of the platform serving todischarge the bound bundle. As the grain-table again starts forward thetension of the oord or band 'a being removed, the counter-weight grestores the bindin gtable to its horizontal position.

The movements of the grain-table C, and consequently the movements ofthe cord-carrying arm II and its companion H', as also of the arms I,are controlled by the gearing U V, Figs. l and 2. The wheel U, which iskeyed or secured upon the main drive-shaft B, is pro vided with teeth orcogs on one-half its circumference onl y, the intervening portion beingcut away, while the wheel or pinion V is fue nished with teeth upon itsentire periphery. It will thus be seen that as the shaft B rotatescontinuously in one direction the teeth of wheel U,- engaging with thoseof the wheel or pinion V, will cause the latter to turn until thecnt-away portion or delay surface of wheel U comes opposite the teeth ofwheel V, when all effect of one upon the other will cease, and each willbecome free to move independently of the other. When the wheel or pinionV is thus released the grain-table is withdrawn by a strong spring, G,or by a cord and weight or equivalent means, causing' the chain or banda to unwind from the reel D, thus turning the shaft S backward andlowering the crank w, and permitting the binding-table to resulne itshorizontal position.

An arm, W, operated by a cam on oneof the shafts B S, bears upon thecord `coming from the reel, and serves to draw it down to or toward thebinding-table.

The arm H', acting in conjunction with thearm H,insures the properadvance of the grain,

and prevents its disarrangemcnt.

The arm O may be provided with a stop to limit its upward movement, andmay also be furnished with a spring to assist in cutting the metal stripand bending and flattening the same, if required.

It will -also be understood that without de parting from the spirit ofmy inventionthe arrangement ofthe drivinggear may be modified to adaptit to'reapcrs of different make or construction. Y

The grooves in which the eudsof the shaft b move permit thecord-carrying arm H to have the required sliding movement for operatingthe arm O.

I am aware that raking-fingers have been arranged to risc in a mannersimilar tothe arms I I, and to move forward through openings in thegrain-platform; but I am not aware that such arms have ever before beenapplied to a sliding platform. By my arrangement the movement of thegrain` over an extended surface, and the consequent'thrashing out oftheheads, is avoided.

I am also aware that a pivoted binding table or platform has beenarranged to tip and antomatically discharge the bound bundle, and this Ido not broadly claim.

Having thus described my invention, what I claim is 1.
